摘要:
An airway device (10) is provided which includes a distal part (12) and a proximal part (20) in sealed communication. The distal part (12) has a distal opening (14) for attachment to a breathing apparatus, in sealed communication with a hollow stem (16). The proximal part comprises a hollow sealing chamber (20) with a proximal opening (22), said sealing chamber (20) having means for sealing within and against the mucosal walls of a body cavity with a corresponding proximal opening, for communicating with the lungs. The sealing means of the sealing chamber (20) includes: a longitudinal fold (32) that allows for adaptation to varying cross-sectional dimensions of said body cavity and said sealing chamber (20) being made of an elastomeric substance and having walls (26,30) that are thicker and relatively less flexible, and walls (24,25) that are thinner and relatively more flexible, said thicker walls (26,30) forming a framework that supports said thinner walls (24,25).
